>> This could happen when the TPM device is reset or replaced.

Isn’t that exactly the desired behavior to defend against physical attacks?

Sure, but most users probably don't actually want this level of defense.

For the same reason that most folks don't use bank vault doors on their house.

Ex - even reasonably technical people hit this footgun in lots of edge cases... like updating their bios, changing the host of a vm running the tool, or having a k8s pod get scheduled on a different node.

I'm surprised this was "default on" at all.

Yes, but it turns out the TPM gets reset quite often on shitty hardware.
